The aqueous solution of foam stabilizer and various foaming agents is used in concrete, magnesite, gypsum, urea-formaldehyde resin and other fields by using the foam produced by foaming machine. Because bubbles are easy to break, the use effect of foaming agent is affected to some extent. Any substance that can improve bubble stability and prolong the half-life of bubble rupture can be called bubble stabilizer.
At present, there are the following foam stabilizers:
1. Macromolecule, such as polyacrylamide, polyvinyl alcohol, protein, polypeptide, starch, cellulose, etc. This kind of substance can improve the viscosity of foam and reduce the fluidity of foam, so it has a certain foam stabilizing effect. However, the operation is complicated, the effect is limited, and the foaming amount is reduced.
2. silicone polyether emulsion can control the structural stability of the bubble liquid film, make the surfactant molecules distributed in the bubble liquid film orderly, and endow the foam with good elasticity and self-repairing ability. Advantages: obvious foam stabilizing effect and convenient use. The disadvantage is that there are many synthetic isomers and it is difficult to control. The application scope is limited to the foam stabilization of anionic surfactants such as sodium dodecyl sulfate (K 12), sodium fatty alcohol polyoxyethylene ether sulfate (AES) and sodium α -alkenyl sulfonate (AOS), which requires temperature.
3. Non-ionic surfactants, such as dodecyl dimethyl amine oxide and alkyl alcohol amide, the foam stabilization mechanism of these substances is to reduce the repulsive force of anionic groups of liquid film anionic surfactants to achieve foam stabilization. The foam stabilizing effect is general. Dodecyl dimethyl amine oxide and alkyl alcohol amide products are various, the quality is difficult to distinguish, and there are many by-products and impurities, which are not conducive to foam stabilizing.
4. Fatty alcohols and fatty acids have similar foam stabilization mechanism with 3, and are insoluble substances, which are extremely inconvenient to use.
